This research work aimed to analyze how the variation in the percentage of natural fibers of Musa Paradisiaca and the chemical treatment influences the mechanical properties of polyester/fiberglass composites. The methodology used included physical-mechanical techniques, such as Fourier transform infrared spectroscopy (FTIR), optical microscopy (MOP) and scanning electron microscopy (SEM), to characterize the fibers and impact failure zones, as well as measurements of impact strength according to ISO 179-1 standard. The experimental design, with a two-factor quantitative approach, considered different percentages of natural fibers 20%, 25%, 30% of 100 mm in length and 155 µm in diameter. And an alkaline chemical treatment was applied (Mercerized 5M NaOH), with evaluations of impact resistance through tests of hybrid sandwich compounds as well as compounds of only natural fibers of dimensions 100 x 50 x 4 mm. The results proved significant variations in impact strength depending on the percentage of fibers and the use of chemical treatment. It was found that the highest percentages of fibers and applying the alkaline chemical treatment at 5M, sandwich-type hybrid composites resulted in a considerable improvement in impact strength due to the greater energy absorption due to a higher fiber load and the increase in adhesion between matrix and fiber due to the elimination of impurities by mercerization., achieving a 13% increase in impact resistance with 81.50 kJ/m2 for a Hybrid composite with chemical treatment of 30% natural fibers R+FN+FV/CT-30%. And an increase of 56% on the with treated hybrid sandwich type composites compared to the treated natural fiber composites. The one-way ANOVA analysis applied indicated sufficient significant differences in impact resistance due to the influence of the natural fiber percentage. In conclusion, this research highlights the importance of the fiber percentage in designing polyester/glass fiber composites, ideal for application in car door panels where high impact resistance is required.
